As far as I can tell, the error of interest is:
Caused by: java.io.FileNotFoundException: /proc/net/xt_qtaguid/stats: open failed: ENOENT (No such file or directory)
A quick google search tells me that its a kernel module that is missing. Any way we can get that module included in the current kernel version, or maybe somehow create dummy files with appropriate content? Just to get the errors to go away. I'm willing to help any way I can.
